Re: virtio-net windows drivers

[Ignazio Cassano <ignaziocassano@xxxxxxxxx>]

Hi all, I executed a complete test to identify the problem.

Firstly I need to exaplain what I am doing.

I created a windows xp guest with sp3 , virtio net and spice agent.

I used virtio-win-0.1-59.iso and spice-guest-tools-0.59.

This is a base image for all other vm xp .

The base image works fine.

I used sysprep on the base image and then I created another xp guest on a qcow2 disk  which uses the base image.

When the new guest starts it does  not get the network card because it asks for drivers.

Confirming the virtio drivers automatic installation (because drivers are present in the base image) and rebooting the guest, 

it can see the virtio network card but it takes a lot of cpu and it cannot be used.

I repeated the test installing virtio-win-01.30.iso drivers and spice-guest-tools-0.3  on the base image.

The new guest now does not ask to install the virtio net drivers but only the virtio scsi adapter drivers and  it works fine.

Could you help me ?

I tried sysprep with several options : either with plug-and play flagged or without it

I tried also using the base image without virtio net adapter, using the rtl net adapter and the guest which uses the base image works fine.

So I think the problem is using sysprep with last virtio net adapter or last  spice-guest-tools .... :-(

Hi, also with spice-guest-tools 1.59 the driver version is: 51.64.104.5900

I found the UsePublicEvents ...it is init.UsePublicEvents and it is disabled

The previous email I sent whas with spice-guest-tools 0.52.

Now I am going to install 0.59

2013/7/15 Ignazio Cassano <ignaziocassano@xxxxxxxxx>

I booted my vm in safe mode and I can see drive information:

Redhat virtio ethernet adapter version 51.64.104.5900

In advanced I cannot see any information about UsePublicEvents

2013/7/15 Ignazio Cassano <ignaziocassano@xxxxxxxxx>

Oh, I am sorry. I must wait a lot for looking information you requested, because when I boot with virtio net enabled the xp vm takes a long time to log on and cpu usage is very very high.

When I'll have information you requested I'll send you.

Many thanks

I am using fedora 17 with kvm ...

I created a bridge and on the same britge windows xp with spice-guest-tools 0.3 works fine.

On the bridge the guest created a virtio net adapter.

I cannot see drivers details in fedora 17 virt-manager

Yan meant driver details on the *guest*:

Device Manager -> NetKVM device -> Properties

In the Driver tab see the driver version.
In the Advanced tab you see driver params.

Hi,

Ignazio - the driver parameters are found in Device Manager -> NetKVM device -> Properties -> "Advanced" tab.

What network configuration on the host are you using?

Bests regards,

Yan.

mmmm

I read something about UsePublichEvents ....Seems it is supported in Fedora 19 but I have fedora 17

2013/7/15 Ignazio Cassano <ignaziocassano@xxxxxxxxx>

Hi Vladim, I do not know what is "UsePublichEvents" ....

where can I check it ?

2013/7/15 Vadim Rozenfeld <vrozenfe@xxxxxxxxxx>

Hi Inazio,

Do you have UsePublishEvents enabled or disabled? If it's on you can try turning it off.
In any case it's better to wait Yan or Dmitry to comment on this issue.

Best regards,
Vadim.

Hi, I think the virtio net driver is released with spice-guest-tool ...
Is it correct ?
In other words ....
I installed virtio net and virtio disk drivers contained in
virtio-win-0.1-59.iso downloaded from fedora.
Then I installed spice-guest-tools-0.59.exe downloaded from spice-space.org.
Seems spice.-guest-tools have their own net driver ....or not ?
